IICKIGAN, ASSIGNOR To run con'cmam mm, 110., or saonuw,IIGHIGAN, n conrom'rron or m YORK mun 3m Application filed September'26, 1930. Serial No. 484,885.

This invention relates to venetian blinds provided with a casein whichthe bl nd operating mechanism is mounted, and is moreparticularly'directed to the mountmg of the transverse roller therein,and on whlch the support and operating cords are wound.

One object of the inventlon is to prov1de a neat and substantial case inWhlCh said roller is mounted, andprovide plates on the ends of saidroller mechanism for removably engaging the ends of said case,

Another object is to provide detachable supports or bearings for usewith blinds of extreme width, so'that the transverse operating rollermay be held in proper alignment, and prevent binding, m salignment, andconsequently faulty operation of the mechanism.

A. further object is to provide a mechanism so constructed that theentire blind structure can be demounted from the window frame as a unit,so that windows can be readi- 1y cleaned, repaired, or as occasion ornecessity may require.

The above and other ob ects Wlll appear as the specification progresses,reference be ng had to the accompanying drawlngs, n which I have shownthe preferred embodlment of my invention, and in which like referencenumerals indicate like parts throughout the several views thereof.

In the drawings: Y

Fig. 1 is a front view of a venetian blind made in accordance with myinvention.

Fig. 2 isan enlarged front view showing the case with the cover removed,and the transverse operating roller mounted therein.

Fig. 3 is a top plan view illustrating the removal 'of-the roller fromthe case.

Fig. 4 is a front view of one ofthe end Fig. 10 is an enlarged frontview illus trating one of the intermediate bearings and its mounting.

Fig. 11 is a part sectional end view.

Referring now more specifically to the drawings, the numeral 5 indicatesa window frame or casing to which a pair of brackets 6 are secured bymeans of screws or the like, a preferably sheet metal case 7 beingdemountably supported on these brackets, and a transversely disposedroller 8 is removably mount- .ed therein.

The roller 8 is preferably formed of pipe and is provided with spacedapart enlarged sections 9 and 10 respectively, blind support cords 11and 12 being anchored thereto so that the cords may be wound thereon,the opposite ends of said cords being secured to the end slat 13 of theblind. A larger section 14 is provided directly adjacent the section 9,and an operating cord 15 is adapted to be wound thereon, and it will beobvious that as the cord is wound on or unwound from the roller, thatthe slats will be raised or lowered accordingly, these enlarged sectionscan be formed of wood or any other desired material, and are anchored inposition on the pipe in any approved manner, or the roller may be asolid shaft, or may be formed in one piece having these enlargedsections formed integral therewith.

i In the construction shown in Figs. 2, 3 and 8 of the drawings, thefront of the case is shown open, and a detachable snap cover plate 16forms a closure for said opening, a slightly different constructionbeing shown in Fig. 9, and in which the top of the case is open, nocover plate being required due to the fact that the top is concealedfrom view when the case is in position on the window frame, however, acover can be provided should it be desired.

The ends of the case are formed of individual plates 17 securely weldedor riveted to the top, bottom and back wall, the top and bottom edges ofsaid end plates being bent inwardly and thenceupwardly and inwardly asshown at 18, to form ways in which end plates 19 and 20 respectively areslidably mounted, the end plate 19 being formed with 55 P 1 of spacedapart slats, the combination with 60 said plates being removable as aunit with 'to engage said threaded member so that when the roller isactuated by operation .of the operating cord, the roller will be shiftedtransversely, and the support cords and operating cord will be evenlywound thereon and raise the slats, rotation of the roller in the reversedirection shifts the transverse roller in the opposite direction, andthe slats are lowered by gravity.

In rollers of extreme length one or more intermediate supports andbearings are provided,- one support and a bearing being shown in Figs.10 and 11, this comprises a vertically disposed plate member 23, theedges of which are turned and secured to the case by welding or rivets,(not shown), the front edge of the plate being shaped as shown at 24 toacv commodate the bearing member 25' in which the pipe member 8 isjournaled, the top and bottom edges of said bearing being grooved toslidably engage the edges of the plate, so that when it is desired toremove the roller, the bearing readily slides out of position.

Suitable openings are provided in the bottom wall of the ease toaccommodate the support and control' cords, and conventional grummets 26are inserted to provide a rounded edge to prevent execessive wear of thecords. Where the window openings are of limited width'it will of coursebe obvious that no intermediate supports and bearings are required, andit will also be understood that the ends of the case may be formed invarious other ways to permit the end plates I mounting.

to be slidably inserted or removed without departing from the spirit ofthe invention. The device is easy and simple to remove, is veryeconomical to manufacture, and is of neat and pleasing appearance, thecase being painted to harmonize, with the woodwork or color scheme inthe home or building. I From the foregoing description it will beobvious that I have perfected a very simple, practical, and convenientvenetian blind What I claim is i 1. In a venetian blind having aplurality a supporting member, end plates removably mounted on saidsupporting member, and a winding roller mounted on said end plates andshiftable endwise as the roller is wound,

- said roller.

2. A venetian-blind including a case, end plates removably mounted insaid case, and a transversely shiftable operating roller removablyjournaled on said endplates and shiftable endwise'as the roller iswound, said roller being removable as a unit with said plates. T I

3. A venetian blind mechanism including a case, a pair of end platesremovably mounted therein and formed with laterally projecting stubshafts, and a transversely disposed winding roller mounted on said stubshafts and removable as a unit with said end plates.

4. A venetian blind mechanism including a supporting member, end platesremovably mounted thereon and formed with centrally disposed laterallyprojecting stub shafts, a transversely shiftable Winding rollerjournaled thereon, said roller being removable as a unit from saidsupporting member.

5. A venetian blind mechanism including i a case, end plates mounted toslide therein and formed with inwardly projecting stub shafts, atransversely shiftable roller journaled on said stub shafts, and havingspaced apart enlarged winding sections, said end plates and roller beingremovable as a unit from said case.

6. A venetian blind mechanism including versely shiftable winding rollerjournaled f thereon and provided with an intermediate bearing, anintermediate support in which said bearing is removably mounted, saidend plates, winding roller, and bearing being removable as a unit fromsaid case.

8. A venetian blind including a case provided with an intermediatesupport, end

plates removably mounted in said case, a transversely shiftable windingroller journaled on said end plates and provided with a bearingintermediate its length adapted to be mounted in said support, said endplates, roller, and bearing being assembled in or removable from saidcase as a unit.

9. A'venetian blind including a supporting member having an intermediatesupport, end plates removably mounted on said support, a transverselyshiftable winding roller journaled thereon and provided with a bearingintermediate its length, and mounted in said support, said end plates,bearing, and roller being removable as a unit from said supportingmember.

10. A venetian blind including a case provided with an intermediatebearing support, end plates removably mounted in said case, atransversely shiftable winding roller, a bearing mounted thereon anddetachably engaging said bearingv support, said end plates,

Ill

roller, and bearingbeing removable as a. unit from said case. I v

11. A venetian blind includin a su porting member, a winding rolleradapt to be shifted endwise as the roller is wound, stud shafts on whichsaid roller is mounted, said stud shafts being removable as a. unit withsaid winding roller.

In testimony whereof I hereunto aflix my signature. 7
